Struct patract_wasmi::ImportsBuilder

pub struct ImportsBuilder<'a> { /* fields omitted */ }

Convenience builder of ImportResolver.

With help of this builder, you can easily create ImportResolver, just by adding needed resolvers by names.

Examples

use patract_wasmi::{ModuleInstance, ImportsBuilder};

let imports = ImportsBuilder::new()
    .with_resolver("env", &EnvModuleResolver)
    // Note, that ModuleInstance can be a resolver too.
    .with_resolver("other_instance", &other_instance);
let instance = ModuleInstance::new(&module, &imports)?.assert_no_start();

Implementations

impl<'a> ImportsBuilder<'a>
